I’m wondering if anyone can identify this engine. It has a
3-1/2-inch bore, 5-1/4-inch stroke, 1-3/8-inch flywheel width and
16-inch flywheel diameter. The only numbers on it are “A303M71A” on
the igniter bracket, and it has a Webster-type AMM magneto. Any
information would be appreciated. Chuck Raith, N9523 Forest Road,
